Samsonov already has one win against Ovechkin and the Capitals this season; he made 24 saves, including stopping all four of Ovechkin's shots, in a 3-2 victory at Scotiabank Arena on Oct. 13.
Samsonov's odds of winning again will increase if he can stop Ovechkin again and avoid becoming the 166th goalie he has scored against. From three seasons of playing behind Ovechkin and practicing against him with Washington, Samsonov knows how difficult it is to stop his shot.
"He shoots as hard in practice as he does in the game," Samsonov said. "There's not much difference but it's still hard to stop the puck. Everyone knows where he's shooting from, the position, but it's still hard to stop because the puck is moving (so fast). But we feel we have a nice team. I believe in our defensemen. I believe in how we play."
The Maple Leafs (19-6-6) had their streak of 15 straight games with a point (12-0-3) end with a 3-1 loss at the New York Rangers with Matt Murray in net on Thursday but are tied with the New Jersey Devils for second in the Eastern Conference with 44 points, four behind the Boston Bruins (48).
Despite missing 12 games with a knee injury, Samsonov has been a big part of Toronto's success. In 11 starts, he is 9-2-0 with a 1.70 goals-against average and. 939 save percentage, best in the NHL in each category among goalies to play at least nine games, and has shutouts in his past two starts, against the Los Angeles Kings and Ducks.
"Guys know him," Capitals coach Peter Laviolette said, "and he was here and a part of the organization for quite a while and he's off in Toronto now and he's doing well, so that's good for him.
"We've got to focus on winning hockey games, so we're going to try to figure out a way to put pucks behind him and win a hockey game. So that's the focus we spend more time talking about."
In three seasons with Washington, Samsonov was 52-22-8 with a 2.81 GAA, .902 save percentage and six shutouts. But he battled inconsistency last season, when he was 23-12-5 with a 3.02 GAA, .896 save percentage and three shutouts in 44 games (39 starts).
The Capitals decided to start fresh with their goalies. In addition to letting Samsonov go, they traded Vitek Vanecek to the New Jersey Devils on July 8 and on July 13 signed Darcy Kuemper and Charlie Lindgren to be their new tandem.
Samsonov remains close with Capitals center Evgeny Kuznetsov and the two communicate regularly.
"We're just tight friends and unfortunate that we can't meet yesterday because they have a tough schedule and the team dinner and all that stuff," Kuznetsov said. "So, I'm looking forward to playing against him in this building. It will be a special day, for sure, for him."
